How many connection really participate in a JTA transaction?

Hi,
In weblogic 5.1 the same connection is retrieved whenever refering to the TXDataSource.
Is it the same in weblogic 6.1 and on? or is it possible that 2 different connections
will participate in the same transaction? if so, how will the commit work - will
it require a two phase commit process?
Thanks in advance,
Avigail.

How many connections PAT can handles?

How many connections that an IP address with PAT can support? One IP address with PAT can support 65536 hosts as there are 65536 ports available for an IP(ranging from 0 to 65535)?

Hi,
PAT (overloading) divides the available ports per global IP address into three ranges: "0-511, 512-1023, and 1024-65535". PAT assigns a unique source port for each UDP or TCP session. It will attempt to assign the same port value of the original request, but if the original source port has already been used, it will start scanning from the beginning of the particular port range to find the first available port and will assign it to the conversation.
Please refer the below URL for details:

Sql Server 2012 Evaluation - How many connection allowed ?

Hi all
I'm testing the replication, everything Works fine, but I'd like to know how many connections allow the evaluation of the SQL Server versión I'm testing on.
We are testing 2 stores with 2 server in replica with about 20 users in each side. So we can get an idea of the prices of the licences my customer have to buy.
Thank you very much.
James Smiths

SQL 2012 license usually is per core and/or per CAL and it depends on the edition.
All editions don't impose any limit on connections but rather on maximum memory, CPUs and other features.
You need first to decide which SQL version suits your needs (and your hardware) and then call for suggestions and prices.

How many connection opened for webdynpro java

Hi,
I have 2 webdynpro java application.The applications sharing the same backend function module.Could anyone tell me
How many connection will be established when the same user wants to open 2 different application but these 2 application shares the same function module.
Thanks
Kanai

Hi,
In webdybnpro ,each Model in an Application utilizes a seperate Connection.If u create JCO connection pool for the User then while connecting to backend
1)The JCO connection pool Manager will open a new connection pool and opens the first connection.
The next available connection from the pool is allocated to the model object.
2)The model object is now able to invoke the required functionality in the ABAP system.
3) When the connection is no longer required by the application, it is returned to the pool.
4) The connection remains logged on to the backend system until either the next application
request is received, or the connection timeout is reached.
5) If no application requests arrive before the timeout is reached, the connection is flagged
for closure.
Note:-If an Application contains 2 models which are connecting to same ABAP system then second Model can be told to share the same JCo connection used by First model This is done by calling its setConnectionProvider() method.

How to determine:how many connections will be needed in RFC adapter setting

Hi XI guru,
We are working on following secnario:
1. JDBC sender selects data from Oracle database, and send this data to SAP XI, XI use async RFC receiver adapter to call a self made RFC, in this RFC, we will call some BAPI and process some ABAP code, then if the reture code is ok, nothing will happen( means data successfully import into SAP ). if the reture code is not ok, another RFC will be called from ABAP code, send an asyn message to XI, XI use RFC receiver to update the message back to Oracle with specific flag.
2. Why we use this secnario is, we want to avoid using BPM, this scenario are mass happening in our project, BPM will slow down the performance.
3. We also don't want to use sync RFC, because BAPI and ABAP code will take sometime to run, we don;t want XI want for the RFC reture message.
The question is:
We successfully run this secnario in unit testing, but when we work on stress testing,found some times we will miss the RFC call. For example:JDBC sender sends message to XI for 10 times in a very short time( we use fault data to make every message has a send back RFC message in stress testing), let's say poll interval 5 sec one time. but send back RFC only be called 7 or 8 times, 2-3 message were missing.
we get back to SXMB_MONI, see all JDBC sender 10 message are successful, and 7- 8 send back RFC messages also successful. No log in SM58 RFC monitor. Then we go to modify maximum connection, and set it to 5, means 5 RFC coconnection possible(as far as I know, this setting means like this, but of course I maybe wrong)
Question is: how can I know how many coconnections I need to setup, and if some RFC calls are missing, is there any place whatever in XI or R/3 can help me to monitor the log, then I can know they are not successful for some reasons,but not just simply miss as they never happened?
That will be helpful, if some one can tell the story of what happen RFC works at background.
Thank you very much for your time and effort on this

HI,
Maximum possible number of initial connections required between sender system and adapter. This value is limited internally to a maximum of 50

How many connections?

Just a quick planning question. This is a church environment that may grow quickly. They're currently trialing with three LinkSys devices and about 25 users. But they anticipate up to a couple of hundred users if successful. Which device(s) would be best for lots of connections? And how many would that be per access point?

The absolute answer is "It Depends" ... just like any other size or implementation question.
For commercial APs from Cisco, the closest thing to "rule of thumb" is ~20 concurrent users per AP, but that number can be adjusted up or down depending on the application, protocols in-use, and overall volume of traffic per user. Also keep in mind that ONE USER radiating an 802.11b signal into your coverage will (may) slow down the system and reduce the potential max count.
I would also humbly suggest you dump the Linksys and go with commercial APs, as they will have more options for fine tuning the power, coverage, rogue mitigation, monitoring, and control.
How many do you need? From the information provided, I'd say 500 or so. You can probably adjust that down somewhat according to the size of the coverage area, building materials, and a mess of other parameters ... without that info, I'll go safe and say 500 ( ;-} .
i.e., How many vehicles do I need to transport the entire senior class of my nephew's high school class at one time? We need to create a solid transportation budget.
Realistically, what you need is a solid site survey that will measure a real signal in the actual environment with real or simulated traffic that is comparable to the expected loads. There is no substitute.
If you are not prepared to do that kind of survey, you should hire someone to come in and do it for you, as this is *critical* information and can save you a mess of money (frustration, reputation) in the long run.
The site survey is where the budget meets head-on with the requested functionality. If you already have a budget planned, then expect to lose some functionality or coverage.
If you already have desires and expectations, then the site survey will provide you the information needed to come up with a reasonable and realistic budget.
As a final note: Just kidding on 500 (in case your sense of humor was broken). A proper spread of APs with the proper antennas can accommodate almost anything ... proper antennas for the coverage area is critical, and selection of same is a big part of the site survey.
Good Luck
Scott

How many connections can make to FMS ?

I want to install Adobe Media Encoder on 40 separate machines, and AMS on another machine.
Each machine has 4-5 webcams connected.
So, I have a web-aplication where users log-in and watch thewebcam they want. My question: how many machines can I connect to one server?(how many Adobe Encoder clients does AMS support?)
Thank You

You can have 10 RTMP connections to AMS 5 trial version. See the below link for more details:

MaxActive?? how many connections should be made available

Can anyone recommend what I should set the maxActive="" property of my database resource connection for a medium to large scale ecommerce application.
How many simultaneous database connections might I expect?
I know this is dependant on the volume of traffic on the site, but I just need a general Idea, I currently have maxActive="100", but I'm a little worried that this may be insufficent for a site that may have up to 5000 concurrent users.
Thanks in advance.

Do you have a formula for the above, to give an
estimated requirement for maxActive connection
settings?
Sorry! there is no real formula but since you are working on a web application the number of connections used will be close to the number of requests at a time on your web application.
And the number of concurrent users dosent give much idear about the number of concurrent requests becouse users dont keep clicking all the time. Most of the time they will be reading somthing on the browser.
Here is a simple calculation but only accurate if you assume that server takes 1sec to process each request.
If the number of concurrent users is 5000 and each user makes a click once in every 60secs, then there will be aproximatly 5000/60 requests/sec. That is 83.333... requests
I assume the only warning sign I will get when
maxActive is reached will be browsers 'hanging' until
it either times out or a connection is released to
the pool?Browsers normally times out and display an error if the server do not respond within a predefined interval (Normaly 90secs) thats what you should watch out for.
By the way if what you want is to make sure the maximum is never reached just set it to a negative value.(Assuming that you are using apache commons pool. negative means infinity)
And set reasonable numbers to MaxIdle, MinEvictableIdleTimeMillis, and TimeBetweenEvictionRunsMillis. Please read the documentation of the setter methods of above attributes if you dont know what above attributes are for.
you can also add a back end page to your web application to display the staticstics of the pool.
such as the number of current idle connections, current active connection and ect...

How many connection of BW

Hi gurus,
I have a doubt , how many BW connection is possible for one r/3 source system.
Thanks

hi Akash,
check Note 775568 - Two and more BW systems against one OLTP system
hope this helps.
Summary
Symptom
Several BW systems are loading data from an OLTP system: Can problems occur during the delta upload?
Other terms
Delta request; Delta queue; RSA7; Time stamp
Reason and Prerequisites
No documentation exists.
Solution
This note replaces the documentation where it is not yet available.
The delta queue always supports multiple BW connections to an OLTP system. The DataSources that use the delta queue function to process their deltas are not problematic, even if multiple BW systems send their delta initialization and delta requests in parallel. This affects most OLTP applications, for example, the logistic cockpit, HR, EC-CS, EC-PCA, CRM, SRM, utilities and so on.
Caution:
The "Several BW systems at one OLTP system" function is not generally supported for the "old" LIS DataSources that are generated on the basis of the LIS information structures. The delta mechanism for these DataSources only provides for one BW system. However, since these DataSources have been almost completely replaced by the cockpit logistics functions, the risk to customers who are just about to plan their BW projects is minimal to non-existent.
However, there is a problem for customers using DataSources with their own time stamp administration.
The problem is restricted to extractors that determine the delta directly via a time stamp during the extraction (for example, CO-OM, FI-AR, FI-AP, FI-GL, CO-PA up to and including PI 2003.1, CFM, CML, generic delta using a time stamp). In this case, currently extracted records are technically sent to the requesting BW on the one hand, and on the other hand, written to the delta queue (RSA7) for a possibly required repeat and even for the deltas of other BW systems. The new time stamp that is then set is used during the extraction for the next delta. If this takes place from a second BW, the process described above is run again, but an additional selection is made according to existing records in the SAPI delta queue that this BW has not yet retrieved. The problem with the second initialization for this type of extractor occurs at this point:
If delta initialization requests run from several BW systems in parallel, the time stamp pointer of the delta administration that is set at the end of the first delta initialization is overwritten by the second one. This may result in data that was already extracted in the delta initialization appearing in the subsequent delta from the first BW system.
The problem occurs with chronologically overlapping delta initialization requests. These problems may also occur with overlapping delta initializations from two BW systems.
With two parallel deltas, duplicate records can appear in the worst cases: If two BWs request delta simultaneously, the time stamps for the upper limit of the selection are taken without the system being aware of the other extraction. However, this is unproblematic as long as the goal is an ODS object with a MOVE update.
To avoid the danger of possible data inconsistencies, complete the Init run from a BW system BEFORE you start an Init or delta run from the other BW system. That is, check on the monitor that the status of the delta Init request is green before you request an Init request from the other BW system. A lock mechanism is provided for CO-OM and is described in note 736394. The other applications mentioned here are currently working on a permanent and satisfactory solution.

Excessive Port 80 TCP Connections? How many connections are normal?

Hi. I'm running MacOS X 10.3.9 on a Mac Powerbook (with all of Apple's latest Security Updates installed. It is a virgin installation and no other software programs have been installed). I then installed Norton Personal Firewall 3.0.2 in order to monitor all my ports.
By default, Norton Personal Firewall (NPF) is not set to log the number of outgoing connections for port 80, although port 80 is the port typically used by most web browsers to contact other sites on the web. If you disable port 80, then your browser will not be able to function or access the web. Therefore it is mandatory that you leave that port open. But what if some unknown hacker wrote a Trojan program to specifically ferry information out of your computer and back to him using that port, then there'd be no way to stop it once the Trojan was in place. If you disabled the port to prevent it, then you'd also disable yourself from the web. If you opened the port for your browser, then the trojan would have free and open access. At least that is the theory that has me wondering about the seemingly high number of outgoing port 80 connections displayed in my NPF logging window. Therefore, I'd very much like to find out if other users who are running a version of Panther with NPF are experiencing the same high connections behavior on port 80.
To create the scenario for this behavior, basically you just open your NPF panel and enable all logging for port 80 (by default it is disabled). For those of you who don't specifically know how to do this, the following is the directions . . .
. . . Open your NPF Service Settings pane. From this pane, highlight the service called Web Sharing Port 80. Click the Edit button at the bottom of the selection window. A new pane will then show the controls named Ports, Logging, and Notification. Bring forward the Logging controls and enable both checkboxes for Allowed and Denied for the Outgoing direction. Click Save and close the window.
Once the above is done, close all other windows and open your NPF Logging window on your desktop and keep it visible for you to look at. Clear all existing entries in the log so you'll start with a clean slate. With everything set up and a web connection available, open your Safari browser (or any browser) to an online web site. On my computer, my Safari bowser is set to open to Apple's website - www.apple.com. Once the browser is open, Apple's website is then displayed.
The result . . . surprisingly, after only a few seconds, a HUGE number of port 80 TCP connections to that website address start to show up and flow into my log. In a matter of only 3 or 4 seconds, at least 250 separate TCP connection entries will show up in my log, and they all have the same web address. If I then click on anything on the page or surf to any other website, the log entries will change to the new site address and start up again, and in some cases, in a matter of less than a minute the number of entries can easily reach into the thousands. I've seen 20,000 entries or more flow into my log after a couple of minutes. And the only way to stop the madness and the entries is to disconnect from the web. Those many entries and this behavior does not seem normal to me, no matter what port is selected and no matter what log settings are enabled. A dozen to 15 or 20 entries for a given site I can understand (I've been told some browsers can open at least 10 connections at a time), but hundreds to thousands, I cannot. I can't understand why any program under any circumstance would need to generate those many log entries in such a short time frame. My problem is I have nothing to compare this data to, I only have my suspicions and have no way of knowing whether this behavior is normal or not. So I am asking for others to make a comparison on their computer if you are running any version of Panther and Norton Personal Firewall and give me your results so I can determine what is normal or not. I've heard of certain hacker attacks called TCP flooding and other forms of attacks, and I don't want my computer to have been secretly taken over by a hacker or the initiator of such attacks unknowingly. Furthermore, this is not anything an average user would even normally notice, simply because Port 80 logging is not usually enabled in NPF. Nevertheless, I need to find out the root of this problem and learn whether this is normal. Other than these high number of connection entries, my web surfing seems normal and I haven't yet experienced any seeming sluggishness accessing sites. Any help anyone can offer I would appreciate. Thanks to everyone in advance.
Here are some images of my own settings and results:
http://homepage.mac.com/starshone/misc/Port80Settings.jpg
http://homepage.mac.com/starshone/misc/Port80Log.jpg
Mac OS X (10.3.9)

But all those connections are how the web works. Each HTML page has dozens or more links. Each graphic or other page element is a new HTTP request on port 80 back to the originating server (or another server even). So it's normal to have a lot of port 80 connections going out if you surf the web.
You can see the individual elements that make up a page in Safari by going to the "Window" menu and showing the "Activity" window. I see CNN's web site tonight has 113 items on its home page. Apple's is 41. My home page is 10. So it's easy to get a lot of connections.
Some applications also use port 80 to check for updates, so you might see the occasional port 80 connection even when you're not surfing the web. These are also nothing to worry about.
